I want to add that I am also one who appreciates this feature. It is a great way to filter out emails from individuals you minimally trust. Another tip is to add the plus sign, followed by any phrase at the end of your email address, before the @gmail.com. I do this for each company I sign up for. This way, I can easily set up filters to catch such emails, and I immediately know where spammers got my email address from. For instance, nimerjaber1@... (my email address) might become nimerjaber1+amazon@... if I am giving Amazon my email address. ALl emails go to the same place, but I can set up filters to move anything with '+amazon' in the 'To' field into an Amazon label, and subsequently either archive or delete any such emails.
